GEORGE W. MORSTATT, OF NFNV YORK, Y.

MACHINE FOR INSERTING PINS IN BLINDESLATS.

forming part of Letters Patent No, 314..,4-64. amd MEI-TCD 24', 1555- Appliration led August l, 1854.

fo @ZZ whom, it may concern.-

Be it known that I, GEORGE W. Mons'rafr'r, ofthe city and county of New Yorlnin the State of New York, have invented a eertainpnew and useful Improvement in Machines for Inserting Pins in Blind Slats, of which the following is a specification.

The object of my invention is to provide a machine whereby metal pins previously cut to the desired length may le accurately and quickly inserted and i'orced into holes previously bored in the ends of blindslats, the pins serving as substitutes for the ordinary tenons on the ends ot' the slats.

My improved machine may be employed to insert a pin in each end otthe slat, and in addition thereto, if desired, asinaller pin in one end of the slat near the edge, the latterserving for the attachment of an adj usting-rod,where bythe slats maybe adjusted as shown and de scribed in my Letters Patent No. 291,924, dated January l5, 188i.

My invention will be fully hereinafter described; and it consists in novel combinations of part-s set forth in the claims.

ln the accompanying drawings, Figure l is a vertical longitudinal section ot' a machine embodying` my invention. Fig. 2 is a plan of the machine, the two hoppers which supply pins thereto being removed. Fig. 3 represents a slat with the pins inserted; and Figs. 4, 5, and 6 are respectively transverse sections on the dotted lines mit, y y, z c, Figs. l and 2.

Similar letters of reference designate corresponding parts in all the figures.

A designates a bed-plate or stationary frame composed of metal and supported on legs or standards A.

The bed-plate or frame A is constructed with a xed head or stock piece, At, at one end, and has guides or ways a in opposite sides, forming a slideway, wherein is tted an adjustable head or stoclgB, capable of sliding toward and from the iixed head or stoekAi This adjustment oi' the head or stock Badapts the machine for receiving longer or shorter blind-slats G to be operated on, as hereinafter described; but if the machine is intended to operate on slats of one lengt-h only the head B may be non-adjustable.

From the adjustable head B a screw-threaded (No model.)

rod, B', extends rearward and through a bearing, b, in the rear end ot' the frame A, and nuts c c are applied to the said rod on both sides of the bearing. 3y turning these nuts on the rod the movement of the rod through the bearing is provided for, and after the head B is brought to the desired distance from the .iixed head Ai the nuts care tightened against the bearing, and the head B is thus held securely against displacement.

Between the fixed and adjustable heads A* B there are two orosspieees, D D', which are notched at di, to receive and properly center the slat C when placed upon them. The piece D is fixed, but the piece D is adjustable in the ways a, and when the head B is moved it is also moved correspondingly, the two pieces D Dsnpport-ing the slat C near opposite ends.

The slat shown in Fig. 3 has at opposite ends pins d, which form the Slat-tenons, and at one end is a smaller pin, cl, with which the Slat-adjusting rod is to be connected.

On the head B is arranged a hopper, E. which is to contain pins d, and on the head A* is a divided hopper or two hoppers, E Eik. which are to contain, respectively, the pins d and d'. The throat er outlet e et' the hopper E is controlled by a feeding wheel or roller, f, which is turned step by step, and tluted or grooved on its periphery to receive the pins, whereby it is made to deliver the pins one by one from the hopper E. The arrangement of the wheel or rollf and its relation to the delivery-throat c ot' the hopper E will be understood from Fig. 4. The outlet-threats e e* of the hoppers E E* are controlled by similar wheels or rolls, f f it, which are also tinted or grooved longitudinally, and have a step-bystep rotary motion. The construction of the rolls j" f* and their relation to the outletthroats of the two hoppers E E* will be nnderstood from Fig. 5.

The shafts of the two rolls ff* are geared together by pinionsff", as shown in Figs. 2 and G, and are operated as hereinafter described, and the shaft j of the roll f is prolonged and extends through the roll f, controlling theoutlet of thehopper E. This shalt is grooved at 2, and the roll j' is locked to it by a spline or feather. TWhenever the head IOO roll f slides along the shaft ffand receives rotary motion from the shaft in whatever position thereon it may be.

In the head A* is a longitudinal slideway, g, in the bottom of which are grooves or seats g y* directly below the outlet-throats e e* of the hoppers E Edi, and into which the pins drop from said hoppers.

In the slidewayg is a slide or plunger, h, which is reciprocated by a connecting-rod, F, and a crank, F, upon a crank-shaft, F2,which is journaled in a bearing, A2, projecting from the frame or bed A.

Upon the shaft F2 is a pulley, F3, to receive a driving-belt. This pulleyisloose on the shaft, and is locked thereto by a sliding`clutchpiece, F, which is Connected n ith the shaft by a spline or feather, 3, and cantherefore move longitudinally on the shaft. This clutch-piece F4 may be operated by a treadle and suitablel connections in any well-known manner; but as such'means of movinga clutch are well-known in various kinds of machinery and are not claimed by me I have vnot shown them.

I have here shown the connecting-rod F as .composed of two pieces connected by a screw- `thread and jam-nut, t' t", and it can therefore be varied in' length, so as to definitely fix the range of movement of the plunger h.

On the under side of the plunger h are attached ribs or tongues lL hwhich iit and slide in the pin-seats ggf in the slideway g and eject the pins from these seats as the plunger moves forward. These tongues h h* are preferably adj ustable,and, as shown in Figs. l and 6, they are fitted in dovetailed grooves in the under side of the plunger or slide, and may be adjusted each by means of a screw, h2, tted in a lug or ear, 4, on the under side of the plunger. At the front end the tongues or ribs h h* have slight depressions,as shown at 5, Fig. 1, and as the pins d d are pointed 'or slightly conical, as shown in Fig. 3, the ends of the pins are prevented from slipping laterally oft1 the ribs or tongues as they are forced forward by said ribs or tongues. y

In the head or stock B is a slideway, j,closed by a cap piece or plate, B and in which is fitted a slide or sliding pin-support, G, which has in its top a groove, 7c, which receives the pin as it is dropped from the outlet-throat c' ofthe hopper E. This piece G is supported at the rear end by springs Z, one of which is shown in Fig. 1, and which are shown dotted in Figs. 2 and 4. The springs press the piece G outward into the position shown in Fig. 1; but its further outward movement is limited by a screw or pin, Z', which is inserted through the cap piece or plate B* and into a slot in the piece G. Being supported by springs at its rear end,the piece G will yield to pressure at its front end, and may be forced back by pressure against the front end.

On the under side of the cap piece or plate B*, and projecting downward into the groove or pin-seat k, is a tongue or rib, k', which is formed with a slight cavity or .depression at its front end, so as to prevent a pin from slipping off it, and when the slide G is pushed inward the pin in the pin-seat k will be held by the tongue or rib 7c', and the slat C will be forced onto the pin.

-Adjacent to the wheel or pinion f3 on the feed-roll f is a stud or fixed pin, m, on which are a ratchet-wheel, m', and a pinion, m2, which rotate together, and the latter of which, m2, gears into the pinion f.

On the stud or pin m is loosely fulcrumed a bell-crank or elbow lever, m3, as best shown in Fig. 6, and whichcarries a pawl, m4, held by a spring, m5, in engagement with the ratchetwheel m. The lever m3 is connected by a link or rod, n, with one end of the lever H, which is fulcrumed at n, and which is acted upon by a spring, n?, to raise that end of the lever H which is connected with the pawl-carryinglever mi', and to.so move the pawl m4 back on the wheel m to take a new hold thereon.

The front end of the lever H bears on a-cylindric hub or roll, I, on the shaft F2, and the said hub or roll has a protection or cam, o, which acts upon that end of the lever H, and thereby moves it against the action of the spring u2, and causes the pawl m4 to turn the ratchetwheel m, and through the gearing above described to also turn the feed-rolls f f* f a sufficient distance to drop the pins d d d into their seats g kga", which are formed in the head A* and in the slide G. When the plunger or slide h is drawn back, the crankshaft is stopped by the clutch, and the slat C is placed in proper position on the notched supports D D, the notches or Slat-seats f being in suchposition that the slat is supported with its pin-holes in line with the grooves or seats g'k git. The crank-shaft F2 isy now started by the throwing of the clutch into gear, and by the :first movement the cam o acts on the lever H to turn the feed-rolls and deposit pins in the pin-seats gk git. This is done while the crank is passing the center, and hence the pins are deposited before the plunger l1. commences its forward movement. As the plunger or slide h moves forward, its ribs or tongues h 7L* strike the ends of thel pins in the pin-seats g git, and so thrust the pins forward and enter them into the holes in the slats. By the continued movement of 'the plunger the slat itself moves forward, the slide G yielding to it or moving with it; but the pin in the pin-seat 7c is prevented from moving by the fixed tongue or rib k', and the Slat is thereby forced onto the pin. During the remainder of the forward movement of the plunger or slide h the pins at both ends of the slats are held by the ribs or tongues h h x atthe oneend of the slat and the rib ortongue c/ at the other end thereof, and thereby the pins are all forced tightly into the slat. At the termination of its return movement the shaft F2 is stopped, and the slat with its pins is removed, and asecond slat is placed on the slat seats or bearings D D', whereupon the clutch is again thrown in and the operation IOO IIO

repeated. As soon as the pressure is removed from the slide G the latter returns to its former position, where it is shown in Fig. 1.

By this machine the slats have their tenonpins,which are commonly made of brass wire, forced into theirpreviously-bored holes tightly and accurately.

The slide G forms a yielding abutment i'or supporting the slat at one end.
